I have 1 kitten who is 3 months old and one adult cat who is 5 years old. Since both cats need different kinds of food (kitten food which has nutrients found in a mother’s milk, and adult formula that has nutrients designed for older cats), I have two separate food bowls. One for the kitten and one for the older cat. The older cat steals food from the kittens bowl which is making her overweight, and the younger one is stealing food from the older cat’s food bowl. I’ve tried mixing some kitten food in with the adult food, but that hasn’t worked. I’ve tried putting the bowls in differnt spots in the house which also hasn’t worked. What would you suggest? Thanks.
